MEANS FOR. APPLYING OOVERINGS TO WIRE.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed January 7, 1909. Serial No. 471,102.

Be it known that I, JOHN ALLEN HEANY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Means for Applying Coverings to NVire, of which the followmg is a specification.

My invention relates to a means for applying fiocculent insulating material, such as flaky asbestos fiber, to a wire, and comprises a particular manner of supporting the flocculent asbestos, so that it may be readily applied to amoving wire whether the wire be rotated about its axis or not. 7

Referring to the drawings: Figure 1' is a diagrammaticview partly in section of an apparatus for applying asbestos to a moving wire; Fig. 2 shows in elevation one form of ball or reel embodying my invention; and Fig. 3 shows a modified form of such ball or reel.

Fig. 2 shows a tape like sheet or ribbon 2, whichmay be of paper, cotton-tape, or the like. 3 is a layer of flocculent asbestos or like insulating material carried by and resting on said sheet or ribbon. The flocculent material, preferably as it comes direct from the carding machine, is applied to the sheet or ribbon 2 and the ribbon is then rolled into a ball or reel as shown in Fig. 2.

In Fig. 3 is shown a modified form in which two sheets or ribbons 4, 5, of paper or tape are used, the sheets with the interposed layer of fiber being then rolled up into a ball asshown.

Referring to Fig. 1, 6 is a pot containing a suitable adhesive mixture such as glue through whichis drawn the wire 7, which receives therein a coating of glue 8. The wlre in its forward movement passes 1n proxlmlty to the sheet or ribbon 2, carrying the asbestos 3, the latter adhering to the glue and forming a coating 9 on such wire. The wire is then passed through a second receptacle 10 containing a suitable paste, such for example as described in my prior patent No. 740,131, or a waterproof coating consisting of a paint or varnish composed of asphaltum or a compound of gum or resin. As the subsequent steps of treating the wire are substantially the same as in the patent above referred to further detailed description of the mode of treatment is unnecessary.

Instead of rotating the forwardly moving wire about its axis, as described in my patent above referred to, I may feed the wire forward without rotating it, and I may mount the ball or reel of asbestos carrying sheet or ribbon in a device which rotates about the wire, the flocculant web being stripped from the carrying sheet by the sticky wire as it moves along. An apparatus suitable for performing this operation is described in my application Ser. No. 472,050, filed January 13, 1909.

I claim:

1. As a new article of manufacture, a flexible sheet or ribbon-like support having a web of fiocculent asbestos fiber detachably supported thereon.

2. As a new article of manufacture, a flexible sheet or ribbon-like support having a web of flocculent asbestos fiber detachably supported thereon and a second flexible sheet or ribbon over said web.

3. As a new article of manufacture,a flexible sheet or ribbon-like support having a web of flocculent asbestos fiber detachably supported thereon, the ribbon and web being rolled up into a ball or reel, substantially as described.

4. As a new article of manufacture, a flexible sheet or ribbon-like support having a web of fiocculent asbestos fiber detachably supported thereon and a second flexible sheet or ribbon over said web, the ribbons and web being rolled up together into a ball or reel, substantially as described.

In testimony whereof, I affix my signature in presence of two witnesses.

JOHN ALLEN HEANY.
